Figure 4From: Rrd1 isomerizes RNA polymerase II in response to rapamycin4-NQO, but not MMS, induces structural changes onto the GST-CTD. A and B) CD analysis of the purified GST-CTD derived from exponentially growing parent (triangle) and rrd1 Δ mutant (circle) that were untreated (opened symbol) or treated (closed symbol) with either 4-NQO (2 μg/ml 30 min) panel A or MMS (1% for 60 min) panel B.Back to article page
